Microsoft Unity. Specify A Certain Parameter In Constructor?
Oct 30, 2010I'm using Microsoft Unity. I have an interface ICustomerService and its implementation CustomerService. I can register them for the Unity container using the following code:
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager());
If CustomerService has a certain parameter in its constructor (e.g. ISomeService1), I use the following code (I need to specify SomeService1):
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1()));
No problems here. The problem appears when CustomerService class has two parameters (not one param as in the previous example) in its constructor (e.g. ISomeService1 and ISomeService2). It works fine when I'm using the following code: container.RegisterType(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1(), new SomeService2()));The problem is that I do not want specify SomeService2() for the second parameter. I want to specify only first parameter - SomeService1(). But I get the error that I need to specify none or both of parameters. How can I specify only first parameter of constructor?
Registering Composite Classes In Unity?
Nov 25, 2010in my implementation, I have an interface as: ICachingManager. I've got now one implementation. I also created a manager class as:
public class CachingManager
{
#region Members
private ICachingManager service;
[Code]....
In case I had one implementation, then I can easily register the CachingManager class with Unity, automatically Unity resolves and injects the ICachingManager.
In case I had more than one implementation using named types, then how can I can make use of Unity? Do I need to make use of an Abstract Factory to decide on which named type to initialize?
Is it a good idea to make use of such a composite class or use directly implementations of the interface with Abstract Factory?
.net - Proper Way Of Using Unit Of Work With Unity Injection
Mar 7, 2011I am using unity, entity framework 4 with POCO classes, repository pattern for DAL and services for Business Logic control.I also want to use Unit of Work so I can package together CRUD operations which I perform on different services and then commit them all together.My question is what would be the proper way to inject the Unit Of Work mechanism into my application using Microsoft Unity?I understand that I can put the IUnitOfWork together with the repository on the constructor of the proper service and then if Unity mapping is specified it would auto initiate the proper instances, but this way I do not pass the global unit of work but rather create a new instance on each level, which can't be a smart way to do it (actually the repository is initiated even before the service).
private IUnitOfWork _uow;
/// <summary>
/// Returns the active object context
/// </summary>
private ObjectContext ObjectContext

MVC :: Unity Setup - Which IOC's Are Most Suitable For MVC3 & EF4, And .Net 4 Framework
Jan 19, 2011I would like to implement IOC and DI and have been looking at the various open source IOC's such as Unity, StructureMap, Ninject, and Castle Windsor, but I noticed that some of them are based on .Net 3.5 framework. Does this matter? Which IOC's would be most suitable or easily integrates for use in an MVC3, EF4, and .NET 4 framework application? Which would be the simplest to implement?
View 5 RepliesC# - Best Way To Integrate Dependency Injection Using Unity When Static Methods Are Used?
Mar 8, 2010Im faced with an impending upgrade to an ASP.NET site and I am thinking of introducing DI using Unity. I have researched the ASP.NET DI side of things and have 2 options (Global.asax or IHttpModule). Im happy to use either. As always, there is a legacy object model in place that I would like to upgrade/change. I would like to go down the route of Constructor injection (passing in the DAO) however, each object has a mix of static and instance methods that both currently call into the DB using SqlCommand objects themselves. I want this removed to provide DB independence, therefore can anyone suggest the best way to do the DI in this case? Im open to drastic changes if they are needed.
public class ExampleClass
{
public ExampleClass(int test)
{
TestProperty = test;
}
public int TestProperty {get; set;}
public int Save()
{
// Call DB and Save

GridView OnRowEditing Events Not Firing When Using Unity 2.0 HTTP Module?
Jan 31, 2011I have an ASP.NET web forms site using Master Pages. It is using Unity as my IoC container. I have created an HTTP Module to build up the container using a couple of tutorials i found online. I need the dependency injection to work for User Controls and the only way i was able to get this to work was to hook into the Pages PreInit event as can be seen from the code below.
[code]....
I also have autoeventwireup set to true on the pages and master page. Can anyone shed any light on why the events are not firing? Is my Unity http module causing this to happen by dropping the event wiring? I can get this to work no problem in a basic example with no IoC involved.

C# - Making Unity And WebForms Error - No Parameterless Constructor Defined For This Object
Sep 7, 2010Does anyone have any good examples of how to make Unity 1.2 or 2.0 work with ASP.NET WebForms?
I thought I had this figured out, but evidently I'm missing something. Now I'm getting the error; "No parameterless constructor defined for this object". I remember getting this error a couple years ago, I and just don't remember what I did.
Obviously Unity isn't working as it should because somewhere along the way I've forgotten something.
Here's some of my code:
Global.asax
